In an experiment carried out in conditions of an open compost plant, investigations were carried out aiming at examining changes taking place in the course of composting of sewage sludge supplemented with sawdust, wood chips and straw in the content of macroelements.}, abstract={The first factor was the kind (composition) of compost heaps and the second factor - duration (number of days) of the composting process. The action of each of the examined factors as well as their mutual cooperation varied.}, abstract={Nitrogen and phosphorus content increased together with the duration of the composting process and the dynamics of this growth was the highest in the compost consisting of sewage sludge, sawdust and wood chips. In addition, mature compost of the abovementioned composition was also characterised by the best fertilisation parameters measured by the content of the analysed constituents.}, type={artykuł}, title={Skład chemiczny kompostów wytworzonych na bazie komunalnych osadów ściekowych, słomy i trocin = Chemical composition of composts manufactured on the basis of communal sewage sludge, straw and sawdust}, keywords={odpady organiczne, komposty, skład chemiczny, makroskładniki, organic wastes, composts, chemical composition, macroelements}, }
